The mineral form of Mohr’s salt is commonly referred to as mohrite. Mohr’s salt titration with potassium permanganate is also a redox titration. In this titration Mohr’s salt acts as reducing agent and potassium permanganate works as oxidizing agent. So, the reaction between Mohr’s salt and KMnO4 is a redox reaction in which oxidation and reduction takes place simultaneously.

Weigh the clean and dry watch glass and record its weight in the note-book. Weigh accurately 4.9 g of Mohr’s salt crystals on the watch glass and record the weight in the note-book. Transfer carefully the weighed Mohr’s salt from the watch glass into a clean 250 ml beaker. 2016-05-24 · You can see the Practical No.1 of Class 12 CBSE Chemistry Course : To Prepare Crystals of Mohr Salt here for free . I have included all the contents ; AIM , Theory , Appratus , Chemicals Required , Reactions , Procedure , Result and Precautions . Mohr’s Salt (ammonium iron(II) sulfate hexahydrate) is often employed as an analytical standard, and has been used in a variety of other applications from nanomaterials to general redox reactions. In this experiment you will mix solutions of iron(II) sulfate and ammonium sulfate to obtain pale Titration - KMnO4 Vs Mohr Salt in Hindi | Full Experiment + Calculations | Chemistry Practical - YouTube.

In this titration Mohr’s salt acts as reducing agent and potassium permanganate works as oxidizing agent. So, the reaction between Mohr’s salt and KMnO4 is a redox reaction in which oxidation and reduction takes place simultaneously. ammoniumjonen i Mohrs salt förhindrar denna reaktion och saltet kan lagras under lång tid utan att Fe2+-jonerna påverkas. Mohrs salt används ibland som ett gräsförbättringsmedel: ammoniumjonerna tillför gödningsämnet kväve och järnjonerna dödar eventuell förekomst av mossa. Förberedelser Läs igenom hela instruktionen. Mohr’s salt is largely used in analytical chemistry. Inhalation of Mohr’s salt causes irritation in the nose and throat.

The solution is cooled to crystallize the compound, which is removed from the solution, washed and dried. with the unknown strength Mohr’s salt solution and the concordant readings were noted. Observation and Calculations: Weight of the Mohr’s salt dissolved in distilled water: 7.8000 g/L Normality of the solution, N 1 = 7.8000 / 392.14 a) Titration with known strength Mohr’s salt solution: Sl. No. needed (ml) Vol. of Mohr’s salt solution (V 1) Weigh two 0.60 gram samples of Mohr’s salt into two separate 250 mL Erlenmeyer flasks. To each flask add 50 mL of the 1 M H2SO4 and swirl to dissolve the salt. Then add 3 mL of concentrated (85%) H3PO4 to each flask. Titrate each solution with the permanganate until a stable pink color (30 seconds) is reached. The redox reaction, Cr2O2−7 oxidises Mohr's salt, FeSO4.
